...like yesterday. Today, by popular demand, there are plans for THREE different do-it-yourself keel guide schemes, thanks to Don Haas, Hank Kwant, and Ken Abrahams. Pictures and descriptions accompany them (the plans--not Don, Hank, and Ken, although I'm just guessing.) Oddly, these are all for 15's, but I don't see why they wouldn't work on any size M-trailer. Good, practical projects.
